To all whom it may concern: j i

Beit known that I, ANsoN P. THAYER, of the city of Syracuse, in the county of Ononldaga and. State of New York,have invented a,

following is a'full and exact description there;

"jgs, and the letters of reference marked thereon-'- Figure l being a plan 'view of my machine, showing one set of the gear-wheels for changside elevation, one of the drivin g-wheels being broken to show the post 1' and attachments more perfectly. Fig. 3 is a vertical transverse sectign' of the cylinder and spades. Fig. 4 is a longitudinal section of the cylinder andcouplinglf'transverse ofthe postl r, showingthe axle, the attachment of th'e shaft F to the coupling I, and the slot of the post r, inv which the end of the axle of the cylinder moves. Fig. 5 is an end view of the cylinder and coupling I, the red lines indicatingthe position of thepost r, the screws .8, and the coupling I when the cylinder is lowered toa working position. Fig. 6 is a plan view of the cylinder, showing the spades attached spirally, so that one spade ceasedv to cut. y

'Thegnature of mynvention consists of a mepower; to plowing and cultivating the soil by means-of-a-rotating cylinder having attached upon .its periphery plows or spades, by means carried to the rear of the machine, where it is deposited bottom side up in a pulvcrized state.

'.llo `enable'.others skilled in the art to make and use inyinvention, I will proceed rto de- I construct asteamboiler of theform shown4 in the drawings and marked a, which is attached to the platform or yfrance-work of the car b, and. suspended upon the' four wheels o in such manner as to equalize the weight as nearly manner, connecting itand the bridge f upon which the boiler rests at the .center of the axle for itsradius a line drawn from it to the cen- 1 ter of thesaid axle. At each end of they guides Il attach "a grooved pulley, j. Upon the top and front end ofthe boiler I attach a shaft, k, and wheel l. To this wheel I connect a pinlon and lineshaftm m, the shaft running to the rear end of. the. boiler, where it has a handwheel, n, for guiding the car. l wind a rope several times around the. shaft k, and each end over one of the grooved pulleys, thence at. taching them to the end of the tongue g. The object of this device is to obtain-a greater \le1-' verage .power in guiding the car, taking the strainfrom the connection of the bridge f and axle d, thereby vadmitting of the weight of the car being .equally distribnted upon all the Wheels and traveling over uneven ground with greater facility.

I construct the platform, of either wood or iron, of a depth of about half the radius ofthe wheels, and of any convenient size. Io the body of the platform I attach a frame-work of beams, 'p p pp, running back a proper distance beyond the'periphery of the drivingwheels. Two of each of these beams are on each side of the car rand sufticientlydistant v'from each other to admit of the-driving-wheels to travel freelylbetween'them. .l f-

'l Iconstru'ct the axlesof the two driving-wheels 'i independent of each vother and of suilicient :length to admitof suspending thebeams from.

theends of the, said axles. At the rear I conneet a cross-beam supporting the whole firmly y together. Upon the inside of this frame-work and, at the center of the driving-wheels I attach, on each side',.an iron posar?, having on `their inner sides a slot in a vertical position.

1 arrange a horizontal shaft with each end in one vof these slots, and a screw, s s, through 'each'end of the shaft, runningfrom top tobottom of the posts, to cause the shaft to traverse frolnto'pto bottom of the posts, say, about two 'feetbr more, if desired.' Upon the shaft ar range a cylinder, t, as seen in Fig. 1, or anyl being increasedior diminished, as'thenature other suitable arrangement for attaching and revolving the spades, to! which 'cylinder I 'attach the spades `or plows.'

.- I construct four sets of spades, una u, at'

equal points of the circumference of the cylinder, projecting from twelve to sixteenlinches `from the periphery of the same, and in the form Aof asector of about one-eightlrof the cr-,` cumference of a circlefand equal in' lengtlr'of the cylinder. These spades are made of cast `steel or iron, plates of aboutA one-.fourth of 4au inch in thickness.' They are attached to the cylh nder by-supports w of thc same material,lseV v cured to, thefspades at the endsand-at three.

orniorejjequidistant points from the ends, and bolted' t'o the cylinder in circumferential lines. The supports w are so tted to the spades that the back part of the same, m, Fig. 3,' are drawn toward the center or the cylind'erfrom atrue circle as much as the spade ismoved' 'forward while it is traveling through one cut. I construct upon the uppe'uend' ,of the'screws s s collars,'l 1olding thcmtfrmlyto the iron posts 1'. Upon thetop of the screw'sl arrange the smallfgearwheels A, connecting through the shaftsB ywith the hand-crank' To the main driving-shaft D',I connect thei bevel-wheels E E and shafts F vThese shafts I suspend upon the driving'shaft D by means v of the couplings Gr Gr. Upon the ends of the shafts F F, I place a tight collar, holding them in the couplings. I also construct upon the shaft on which the cylinder revolves the coup- 4lings I I, which are bored 'at the ends K, ad-

mitting the other ends of the shafts F after passing through the small bevel-wheels L L,

which, together with their keys, are so con-` structed as to admit of the shafts F-sliding freely. l attach to the ends of the couplings I knee-pieces M M, which'pass behind ,the .wheels L L, holding them always against the ends of couplings I; mits of raising the cylinder upon astraight line and keeping' the gearings E .E and L L always in working position. wheels L L work iuto large segment-wheels upon the cylinder revolving the same, as seen 'atN,I"ig.2.

Upon the main shaft D and counter-shaft l?, I arrange three or more pairs of gear-wheels,

Q two of which, l and 3, are keyed fast upon', the main shaft and one, 2, is also keyed fast uponfshaft l?, the others beingjloose when not heldffast by the pin R. into and through a hole bored in either of the loo'sewheels opposite' to holes bo'redin the wheelsthat are keyed fast, transmits the mo# tion through each set respectively, thus changf ing the relative motion of the cylinder` and drivingwhe'els. The object intended to be secured by this arrangement is enabling the spades to cut tiner cuts inhard soils and larger cuts in softer soils withoutchanging its velocity, the cylinder being constantly kept at the same speed, but that of the drivin g-whecls This arrangement ad- The small lbevel-i The pin E being put I construct the large bevel-wheels S, F.ig, 2, upon the arms of the two drivin g-wheels of the car' and the small wheels and intermediate shaft for communicating the power fromthe engines forpropellin g the car overthe ground.

'I construct the'engines of any'ordinarykinds, of smalLsize, and attach them to thev platform,

bymeans of the small and large gearingtothe proper speed. ofthe driying-whsels-j-sayjw 'hundred revolutions 'of the'en'gines'td two br four ofthe driving-wheels'per minute.

I construct the body ofthe ,can so as to carry .waterfor the supply of the' boiler," fuel'being the boiler, in boxes resting upon Athe '-platform, The frontend of the boiler is'. de 'ressed so going upl or down any ordinary hill without running off the tubes at either end.l t

The operation is as follows: Motion being communicated by the steamengines through 'the main shaft-D, the car begins to moveand the cylinder to revolve -while it is suspended ator,`b'y`means of the hand-crank C, proceeds cylinder revolves 'in the, same directinasbthe long at top, according'to the motion "iv'enby 4circle described by the edge ofthe'spadesvfand from tw'o feet to two and a half lougiQm-heel spades, and are'carriedtherciuuntil the spades have arrived at or near a vertical position .in the rear of the machine Y, Fig.2, when they` slide out .and fall to the ground, thatfwlich-` handfwheel krt.' y
